10. Changing the Target Lo CO2
The default Target Lo CO2 level is pre-set at 800 ppm.Depending on the types
of plants you are growing, you may wish to change the Target Lo level. To
change the Target Lo:
1. Press the SEL/ENT button once. The TARGET Lo icon flashes.
2. Press SEL/ENT button for 2-3 seconds to enter Target Lo mode.
3. Press the UP or DOWN buttons to adjust the Target CO2 level.
4. Press the SEL/ENT button again to Save the Target Lo value.
11. Changing the Target Hi CO2
The default Target Hi CO2 level is pre-set at 1,500 ppm. Depending on the
types of plants you are growing, you may wish to change the Target Hi level.
To change the Target Lo:
1. Press the SEL/ENT button twice. The TARGET Hi icon will flash.
2. Press the SEL/ENT button for 2-3 seconds to enter the Target Hi Mode.
3. Press the Up or Down buttons to select Target CO2 value.
4. Press SEL/ENT button again to Save the Target Hi Value.
12. Calibration
Between growing cycles or at least once a year, you should manually recalibrate
the unit. We recommend you use fresh air (~400ppm) for calibration by taking
the unit outdoors, plugging it in, and following the procedure below. Optionally,
you can calibrate using a cylinder of known CO2 gas (0~2000ppm) connected
to the “M” fitting. Wait at least 5 minutes for the CO2 level on the LCD to stabilize,
then follow this procedure.
1. Press the SEL/ENT button 3 times. The CAL icon will flash.
2. Press the SEL/ENT button for 2-3 seconds to enter the CAL mode.
The CO2 level on the LCD will flash.
3. Press the UP or DOWN buttons to select the CO2 calibration value.
Select 400ppm for outdoor/fresh air, or select the number that
matches the known CO2 gas cylinder rating.
4. Press the SEL/ENT button again to start calibration. Calibration will
take 3-5 minutes.
5. If the word PASS is displayed, calibration is complete.
6. If the word FAIL is displayed, retry the procedure.
7. If the word Er9 is displayed, refer to Error Codes below.
13. Advanced Menu
The advanced menu is for modifying the Daylight and Barometric Pressure
functions.
To access the Advanced Menu:
1. Press and Hold both the UP and DOWN buttons for 10 seconds.
2. The screen will show LED.
In Greenhouse mode, the Daylight Mode uses the Photo Sensor to detect light.
The Power LED (Red) shows power to the unit. The default mode is LED OFF
at night. If LED is ON, the Power LED (Red) will remain on at night.
Note: Some growers believe an active Power LED (Red) at night provides
enough light to continue the photosynthesis process.
To change the LED mode:
1. With LED showing, Press ENTER.
2. Press UP or DOWN to toggle between YES and NO.
3. Press SEL/ENT to Save.
The Barometric Pressure function compensates for altitude adjustment. The
default setting is BAR ON. If BAR is OFF, the unit will default to sea level
barometric pressure and not compensate the CO2 level for altitude.
Note: CO2 levels are effected by altitude and could show incorrect readings.
To change the BAR Mode:
1. With LED showing, press UP or Down to show BAR, Press ENTER.
2. Press the UP or DOWN button to toggle between YES and NO.
3. Press SEL/ENT to Save.
14. Reset Factory Defaults
RCFS fixes improperly set Target or manual calibration problems and returns the
meter to Greenhouse Mode by restoring the factory default settings:
Note: If you reset the Factory Defaults, the controller will revert to Greenhouse
Mode. If you are using a fan, you should immediately change to Ventilation
Mode for the device to work properly for your application (See step 10 -
Changing the Mode).
1. Press the SEL/ENT button 5 times. The RCFS icon will flash.
2. Press the SEL/ENT button for 2-3 seconds to enter the RCFS mode.
3. Press the UP or DOWN button to select “Yes”.
4. Press the SEL/ENT button to Save and reset factory defaults.
